The Cannabis Paradox: How THC Promotes Weight Loss but Jeopardizes Vital Nutrients
A University of California, Irvine study reveals that regular usage of cannabis can contribute to weight loss, but it’s accompanied by significant downsides.
Adolescent Exposure to THC and Energy Balance
The research discovered that adolescent exposure to low-dose THC, the main component of cannabis, interferes with the balance of energy and fat storage in adulthood.
Leaner Body and Decreased Risk of Obesity and Diabetes
This leads to a leaner body and a decreased risk of obesity and diabetes. However, the changed processes also hinder the capacity to utilize stored nutrients, which are essential for brain and muscle activity.
Abnormal Protein Production and Impact on Physical and Cognitive Functions
The fat cells produce abnormal quantities of muscle proteins, which may negatively impact physical activity and cognitive functions, such as focus. Regular cannabis users, even with their increased appetites, generally have a lower body weight and reduced risk of diabetes in comparison to non-users.
Explanation for Contradictory Occurrence
However, a recent study by researchers from the University of California, Irvine provides a potential explanation for this seemingly contradictory occurrence, and the implications are not encouraging.
Disruption of Energy Storage Processes during Teenage Years
Many adults who consume cannabis frequently started using it during their teenage years. The study reveals that cannabis can disrupt the finely tuned processes that govern energy storage during this critical period of physical development.
Remarkable Molecular Alterations in Fat Stores
These changes are deeply linked to remarkable molecular alterations within the body’s fat stores, or adipose organ. After exposure to cannabis, these fat cells begin to produce proteins typically only found in muscle and heart tissue.
Impact on Fat Cell Function and Nutrient Storage
To understand these results, the researchers delved into the molecular changes caused by THC. They found that while the fat cells of THC-treated mice looked normal under a microscope, they produced excessive muscle proteins, typically absent in fat. Conversely, the muscles produced fewer of these proteins.
Effects on Physical Activity and Mental Processes
The researchers concluded that the strain of producing these ‘foreign’ proteins disrupts the normal functioning of fat cells, thereby affecting their ability to store and release nutrients. This disruption could impact both physical activity and mental processes like attention, both of which rely on a steady supply of fuel to the brain.
Implications on Physical and Mental Health
Daniele Piomelli, PhD, director for the UCI Center for the Study of Cannabis, said, “We often view cannabis only as a psychoactive substance, but its effects extend beyond the brain. Its main ingredient, THC, mirrors a group of chemical messengers called endocannabinoids that regulate important functions throughout the body. Our results demonstrate that tampering with endocannabinoid signaling during adolescence permanently disrupts adipose organ function, which may have far-reaching implications on physical and mental health.”
Funding and Conclusion
The National Institute on Drug Abuse primarily funded this study.
